The recent history of Arkansas Razorbacks football defense, in two charts:
These two X-Y charts include statistics covering Razorback football since 1995, which is as far back as I can find team sack statistics. Sacks and sack yards lost count as running plays in NCAA stats, and they often conceal teams' true run defense. In these charts, sacks are counted as pass plays. Pass rush is a vital component of pass defense, and pass defense stats should include their effect.
I marked the Bobby Petrino years, plus the 2012 post-BP season in limbo, in red on these charts. Immediately, one notices two things:
- Run defense looks chronically poor in the Petrino years.
- Pass defense had made considerable progress, until now.
- Opponents are completing 62% of their passes, with almost three TDs per game.
- The pass rush is getting to the QB once ever 24 pass plays, worst since 2003.
